Ailment: Redness and swelling of the membranes that line the eyelid and eye surface.

Odd Cure: Direct application of fresh lemon juice.

Rationale: Pink eye may have bacterial and/or viral causes. Lemon juice should create an inhabitable environment that is tolerable for the eye but not the infecting agents. One individual claims to have successfully treated his pink eye with lemon juice on two separate occasions and a similar approach using vinegar as the acid is suggested (ref). However, lmeon juice may cause nothing but additional irritation (ref) and overall, lemon juice succeeded in one YouTube video (ref) but failed in two others (ref and ref). Lemon juice may work, but only for specific types of eye conjuctivis.
